Angeline Lillard, David Loeb, and Karen Manship will present and be available for questions regarding their recent 3-year study of public Montessori outcomes, published in PNAS. It is the largest study of public Montessori preschools, conducted in 24 public Montessori schools across the US, with 588 children who were randomly assigned to attend Montessori or who lost the lottery to attend. The rigor of the study and strength of the outcomes make it one of the most important research studies of Montessori yet.
